Evaluation of under sleeper pads influence in the test section in Planá nad Lužnicí railway station
Švanda, Tomáš ; Langer, Vojtěch (referee) ; Hruzíková, Miroslava (advisor)
Under sleeper pads (USP) are elastic layers positioned on the bottom surface of sleepers. Their aim is to slow down a deterioration of track geometrical parameters and reduce track maintenance costs. Three test sections with under sleeper pads have been built on the railway network in the Czech Republic. The effect of the under sleeper pads is continuously monitored. The height level of rails is measured by precise levelling. This thesis is focused on the Planá nad Lužnicí test section. It describes the precise levelling measurement in the 2015 and its evaluation and comparing with previous measurements. Furthermore track recording car measurements were evaluated.

Sports and cultural centre, Otradov
Myška, Jan ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The subject of this diploma thesis is the preparation of project documentation for the implementation of new sports and cultural centre Otradov. The dominant feature of the complex objects stands and multipurpose hall. The building is architecturally designed with an effort to fit in too much of rural architecture. Multipurpose hall has two floors, one third roofed flat roof, two-thirds of the roof ridge. The core system is aerated concrete blocks. The building is two-storey grandstand with the carrier deck. Roofing is solved by means of broken wooden beams. Sanitary facilities is dealt wall system and roofed shed roof. Athletics track, the surface of the polyurethane mixture designed for sports.

Preparation and realization of the railway viaduct in Ostrov nad Oslavou
Šťastný, Jiří ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
This Diploma thesis deals with the preparation of the realization of the railway viaduct in Ostrov nad Oslavou. Realization of major technological stages is addressed in building technological study. Technological processes of each sub-job phases are supplemented by technical regulations, the design of the main building machines and mechanisms, inspection and test plan, schedule of occupational health and safety, time and financial plan construction, construction budget, a plan for securing material resources. I also worked out the technical report of the building sites facilities including drawings needed. I also worked out design rehabilitation of the substructure of the railway viaduct, which is consist of technical regulations for remediation work and drawings.

Design of RNAV SID and STAR air routes for Brno-Tuřany airport
Zvolánek, Jiří ; Ing. Duka (referee) ; Vosecký, Slavomír (advisor)
The main content of this master’s thesis is design of RNAV SID and STAR routes for Brno Tuřany Airport. The study analyses usage of current conventional instrument arrivals and departures published for the aerodrome and describes its TMA. The new precision RNAV routes and the terminal area are designed based on the indentified information. A detailed construction of the chosen departure procedure is enclosed.

Chrudim Station Redevelopment
Filo, Martin ; Motl, Daniel (referee) ; Říha, Tomáš (advisor)
The subject of the diploma thesis is to design a redevelopment of railway station Chrudim in order to meet current legislation on access of persons with reduced mobility. Two platforms with the platform edge height of 550 millimetres above the top of the rail have been designed. The amount of four running tracks through the station remains unchanged. Furthermore, the railway superstructure, railway substructure and the new drainage system was also designed.

Development of Long-pitch Corrugation in Curves of Small Radii
Valehrach, Jan ; Kohout,, Martin (referee) ; Lidmila,, Martin (referee) ; Plášek, Otto (advisor)
Throughout the operation, the rails are worn and deteriorate. With the increasing speed of rolling stock, along with higher track loads and especially in the vicinity of major traffic hubs with a higher frequency of trains, defects that did not occur to such an extent before or were not considered to be significant, are brought to the forefront of the concerns of track infrastructure managers. Even though these defects are not directly restrictive to traffic operation, they are, in any case, a source of noise and vibration. One of these defects on the railway track is the micro-geometry defect of the running surface of the railhead. In directional curves with radii of less than 600 m or 700 m, defects known as long-pitch corrugation occur on the inner rail. In curves with 300 m or smaller radii, these waves are so distinct that they are a significant source of noise and vibration. In particular, vibrations affect the track surroundings and the track itself, as they cause other defects in the track structure. This dissertation deals with long-pitch corrugation, focusing on the monitoring of wave generation and development over time. The verification of the possibility to track the development of slip waves over time is the basis for possible future models predicting the development of defects. Numerous measurements of geometric parameters of the track and microgeometry of the railheads, specifically slip waves, have been carried out in the framework of the problem. Using RMS and peak-to-peak methods, the rate of development of defects over time and the relationship with other track parameters were evaluated. Based on the obtained development curves, intervals for further maintenance interventions were estimated. A part of the thesis focuses on the deficiency or excess of cant concerning the development of long-pitch corrugation.
